> Garmin's unwavering commitment to physical buttons and how you can customize what they do is what makes them the gold standard in this area for me. Most people may be unaware that Garmin has a strong foothold in the stringently regulated avionics industry, in particular in flight instruments, displays, deck and others human-machine interface products. In turn, specific regulations informed by ergonomics research are unambiguous in prioritizing safety and unanimously contain minimum usability requirements. As an example, an AC [1, Ch. 7] advises on (electronic display) control devices, and another AC [2] advises on design and evaluation of controls and displays. The software-defined counterparts have immensely harder requirements that must be satisfied, which, in my reading, is incompatible with pure touchscreen devices.
